摘　　要：煤层气开发老区L型加密水平井的技术方案,即通过在低产井的井间添加加密水平井,建立起单井之间的有效井间干扰,使整个区域实现整体降压,从而达到提高低产井单井产气量的目的。本文通过从布井、储层保护、钻井及排采四个方面分别提出了老区加密井在具体实施过程中需要注意事项,为煤层气开发老区加密井钻井及排采提供了一个系统的可行的技术方案。The technical solution for infilled wells in the produced area of coalbed methane development involves infilling horizontal wells be-tween low-production wells,establishing effective inter-well interference,achieving overall pressure reduction in the entire area,and thereby realiz-ing the goal of increasing the gas production rate of low-production wells.Based on the analysis of the four aspects of well deployment,reservoir pro-tection,drilling and production,this paper puts forward the problems that should be paid attention to in the specific implementation of infilling wells in the produced area,which provides a systematic and feasible technical solution for the drilling and production of infilled wells in produced areas of coalbed methane development.
